A tobacco vaporizer further includes a sealing part located between the vaporizer and the battery rod, a temperature measurement detector that one end of the temperature measurement detector is inserted the sealing part and the other end of the temperature measurement detector is connected with the PCB board through the conductive wire.

The vaporizer includes an evaporation cavity and a heating device placed in the evaporation cavity.

One end of the vaporizer connected to the evaporation cavity includes a through hole; the sealing part is inserted the through hole.

The temperature measurement detector runs through the sealing part or is inserted the inner of the sealing part.

The vaporizer and the battery rod are in threaded connection to each other.

The tobacco vaporizer further includes an inner electrode and an outer electrode, an interlayer located between the inner electrode and the outer electrode.

The interlayer is made of insulation silica gel.

When implementing the tobacco vaporizer of this invention, the following advantageous effects achieve, the tobacco vaporizer is benefit for measuring the temperature of the evaporation cavity by setting the sealing part between the vaporizer and the battery rod, and inserting the temperature measurement detector in the sealing part. At the same time, there is a control circuit in the tobacco vaporizer. Wherein such control circuit can analyze and dispose a temperature measurement signal and control the battery to provide power to heating device while the temperature measurement signal detected by the temperature measurement detector transmit to the control circuit. All of that make the heating device offer the optimum temperature for the tobacco to occur pyrolysis. The tobacco vaporizer is simple in structure and easy to achieve.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

In order to understand purpose of the present invention more clearly, a detailed description is give in the specific embodiments referring to the drawings. It is to be understood that all the specific embodiments described in this invention are not to restrict the present invention, only for illustrating the present invention.

Referring to FIG. 1, FIG. 2, FIG. 3, and FIG. 4, the tobacco vaporizer of the present invention includes a vaporizer 1, a battery rod 2, and a PCB board. The tobacco vaporizer further includes a sealing part 4, which is located between the vaporizer 1 and the battery rod 2. The tobacco vaporizer further includes a temperature measurement detector 5 that one end of the temperature measurement detector 5 is inserted in the inner of the sealing part 4 and the other end of the temperature measurement detector 5 is connected with the PCB board through the conductive wire.

The vaporizer 1 includes an evaporation cavity 6 and a heating device 7 placed in the evaporation cavity 6. A current circuit is consisted of the heating device 7, the PCB board and a battery. Such current circuit can control the battery to provide power to the heating device 7 through the PCB board.

At end of the vaporizer 1, there is a through hole 8, connected with the evaporation cavity 6. The sealing part 4 is inserted in the through the hole 8. The temperature measurement detector 5 runs through the sealing part 4 or inserted in the inner of the sealing part 4. In specific, as shown in FIG. 2, there is a hole in the sealing part 4. If the hole is the through hole 8, the temperature measurement detector 5, which runs through the sealing part 4, gets in touch with an air in the evaporation cavity 6 and measure the temperature of the evaporation cavity 6. The sealing part 4 is silica gel stopper or is made of other materials. As shown in FIG. 4, if the hole is blind hole, the temperature measurement detector 5 inserted in the inner of the sealing part 4. The sealing part 4 is made of thermal conductive materials, such as thermal conductive silica gel and so on.
